Figure Lengend Snippet: Characterisation of elemental composition and spectra of Chitligsan. (A) Constituent elements and EDS image patterns, (B) XRF results, and (C) FTIR spectra of Chitligsan.

Article Snippet: Additionally, to evaluate the effect of Chitligsan against antibiotic-resistant bacteria, methicillin-resistant S. aureus (MRSA ATCC 43300) was investigated; however, no discernible inhibitory activity was detected under the tested conditions.

Techniques:

Analysis of the XRD patterns of Chitligsan. Calcite was the most abundant mineral (42.8%), followed by hydrotalcite (40.3%), clinopyroxene 15.6%, and ilmenite 1.3%.

Proposed formation mechanism of Chitligsan. Desert sand minerals (Fe 2 O 3 , FeOOH) interact with oxalic acid and light, promoting Fe( iii )/Fe( ii ) redox cycling through chelation and partial reduction under light and moisture, leading to the formation of the mineral composite Chitligsan.

Techniques:

Antibacterial activities of Chitligsan samples, prepared with distilled water and 0.1 M citric acid, against E. coli (ATCC 25922), S. aureus (ATCC 29213), and P. aeruginosa (ATCC 27853). Supernatant: supernatant of Chitligsan suspension, blank: distilled water (DI), ciprofloxacin (CIP) (5 µg mL −1 ), 1: Chitligsan DI extract (1 mg mL −1 ), 2: 0.1 M citric acid (control), 3: Chitligsan 0.1 M citric acid extract (1 mg mL −1 ).
